Anyone use them? And what is your opinion and yardage? Thank You in advance

I use them and swear by em
I shoot them out of my 870 and my muzzleloader, I have only shot them out
to 100 yds with open sights but the accuracy and performance are awesome.

I use them in my Encore 20ga with tremendous success.
1 hole groups @80 yds.

I killed a doe with them at 50 yards and they smoked here real fast. Try several slugs in your gun to see which patterns the best for you. They all do a good job on deer. The only slug that I dont care for are the winchester bri slugs.they are accurate but the lead is too hard for good expansion. But they do kill deer as they have for me.
